Abstract

The invention relates to a Raman converter of improved design, which does not require an exact alignment of the optical elements. There is provided a backward Raman converter which comprises a Raman medium which converts a laser radiation of a given wavelength to a different wavelength by Raman scattering, which comprises a dichroic coupler positioned between a pump laser at the one side of the Raman medium, directing the laser beam into the Raman medium, reflective means being positioned on the second side of the Raman medium, which reflects the Raman-shifted radiation back into the Raman medium, wherein the radiation is amplified by the interaction with the Raman medium and with the incoming pump laser beam The amplified Raman shifted beam is coupled out of the system by means of the dichroic coupler.
